Rapid Drill Results Using detectORE? in West Africa
Portable PPB Pty Ltd
Explore Smarter. Discover Faster. Using our simple, safe, detectORE? in-field low level gold by pXRF technology.
Executive Summary
Results from exploration drill samples in Africa can suffer lengthy delays. Sorting, packing, and transporting samples can be time-consuming and challenging. Results can take many weeks after reaching the lab, impacting the opportunity for follow-up drilling.
With detectORE? gold analyses are available anywhere, the same day as drilled.
The Problem
Drilling is a costly activity, and it is hard to commit to action until assay results are received. Drill rigs are a finite resource and are not always available. With substantial costs to mobilise, effective rig utilisation is critical.
Yet, this is too often impacted by a lack of data to drive the next steps. With logistics and lab bottlenecks gold results can take months during which time a project or company can languish awaiting results to provide confidence on the next activity.
Exploration projects and companies thrive or fold on gold results.
“With detectORE? gold analyses are available anywhere, the same day as drilled.”
The Case Study
detectORE? was tested on RC samples from 18 carbonaceous and arseniferous drill holes from West Africa. The detectORE? results were compared with the original fire assay on these holes showing strong correlation between the methods. The RC samples were sieved to less than 1mm, followed by our proprietary leach, collection and pXRF analysis which successfully identified the areas of mineralisation to allow same day decisions.

Conclusion
Our simple, in-field gold analysis technology works effectively on RC drill samples from West Africa. This takes away to need to transport all samples from the field and wait for results that can take months. Waiting for results is a slow, inefficient, and ultimately very costly method of gold exploration especially when seasonal and commodity cycle effects are factored in. The detectORE? method is ideally suited for identifying and differentiating ore grade intercepts, anomalous and barren material downhole. This provides in-field confidence on whether to advance or retreat from a target. This case study demonstrates the effective use of detectORE? for African RC saving time and resources to explore smarter and discover faster.
